Thanks to @Tinwarble for the heads up, I've been testing an alternate @fritsch's Kodi 17.2RC1 build.

kodi-20170411-91c472b-notsoshitty-armeabi-v7a.apk

This can be installed straight over any existing Kodi Krypton already present. No Settings are lost.

This release works around the broken H264 and mpeg2 Deinterlacing issues whenever a OTA TV channel is changed.
However 4:3 Aspect Ration detection is buggy for mpeg2 720x576i here.
That can be worked around with a tweak to Kodi Settings > Player > Videos > Display 4:3 Videos as Stretch 16:9

Deinterlacing still appears to be Half motion only, so 25fps fast action sports with moving footballs will display multiple footy trails onscreen on the Mi Box. Full motion deinterlacing (50fps in this case) would give you a sharp, high quality picture output with solid images if it was working properly.

Marshmallow Firmware on the WeTek Hub, produces correct Full Motion Deinterlacing with this Kodi Krypton. Even then its not reliable.
(hint turn on Kodi Logging and watch the fps readout)
